Description
Technical field
The present invention relates to a kind of desert structure, more particularly to a kind of barren green desert earth's surface windproof structure, belong to control of desert
Technical field.
Background technology
Desertification is a global ecological environment problem.According to incompletely statistics, desert and Desertification Soil are in Africa
55% is accounted for, North America and Sino-U.S. account for 19%, and South America accounts for 10%, and Asia accounts for 34%, and Australia accounts for 75%, and Europe accounts for 2%.It is Chinese waste
Desertization land area is 262.2 ten thousand square kilometres, accounts for the 27.4% of area, and nearly 400,000,000 population is influenceed by desertification, together
When, the direct economic loss caused by desertification endangers is up to 120,000,000,000 yuan every year.
At present, research of the scholar to desertification is concentrated mainly on land sandy desertification aspect.Conventional Desert Control
Means have plant to afforest, sand-protecting barrier, straw checkerboard barrier etc..But simple tree planting difficulty is very big, plant length of embedment needs very big, plant
Survival rate is very low, and slowly effect is, it is necessary to put into substantial amounts of man power and material.Sand-protecting barrier, straw checkerboard barrier instant effect, but input also compares
Greatly, it is difficult to large area is used.Emerging means also have soil surface skinning technology, have chemistry, physics and biological breadcrust, merely
Physics and chemical skinning it is very fragile and unstable, while chemical skinning also has certain pollution to surrounding environment.And biological knot
Skin is to produce a large amount of mucus in growth by bacterium, fungi, blue-green alge etc., and these have sticky appendicular thalline and viscosity
Liquid is combined into skinning by the crosslinking with algae substances, but the method has certain requirement to environment, and skinning is slow-growing,
Slowly effect.
The content of the invention
